Re: [PHP] Unexpected behavior of max() function

[Rodrigo Silva dos Santos]

A solution to it is, if you can, enter the array itens without the 
commas, just array(100,110.453351020813,9);

As the output tells you, you are comparing strings and the character 
'9' is greater than the character '1' (at the beginning of the two 
other strings).

[PHP] Unexpected behavior of max() function

[Рогулин С.В.]

Hi, dear subscribers.

I encountered with unexpected behavior of max() function. When i pass a 
parameter ['100', '110,453351020813', '9'], this function gives answer '9'


var_dump(
  max(array('100', '110,453351020813', '9'))
);

// will output:
// string(1) 9

I can`t understand this behaviour. Please explain this behavior.

PHP 5.4.7 on FreeBSD 9.0-RELEASE-p4 amd64

P.S.
Sorry for my english :(

Because it returns alphabetical highest string.
You should change your locale or use dot instead of comma:

var_dump(
  max(array('100', '110*.*453351020813', '9'))
);
